void seed( result_type value = default_seed ); | (1) | (since C++11) |
template< class Sseq > void seed( Sseq& seq ); | (2) | (since C++11) |
Reinitializes the internal state of the random-number engine using new seed value.
Parameters
| value | - | seed value to use in the initialization of the internal state |
| seq | - | seed sequence to use in the initialization of the internal state |
Exceptions
(none).
Complexity
Example
#include <iostream>
#include <random>
int main()
{
std::mt19937 gen;
// Seed the engine with an unsigned int
gen.seed(1);
std::cout << "after seed by 1: " << gen() << '\n';
// Seed the engine with two unsigned ints
std::seed_seq sseq{1, 2};
gen.seed(sseq);
std::cout << "after seed by {1,2}: " << gen() << '\n';
}Possible output:
after seed by 1: 1791095845
after seed by {1,2}: 3127717181
